Method and system for controlling display viewing environment in vehicle

Abstract

Disclosed is a method for controlling a display viewing environment of occupants in a vehicle with occupant seats forming multiple rows. The method includes, in response to a result of a viewing state determination being that a first occupant of a first seat in a first row of the vehicle, and a second occupant of a second seat in a second row of the vehicle, are in a state of viewing a front display together, performing reclining or vertical level reduction of the first row seats in response to a determination that occupants of the first row seats and the second row seats are in the state of viewing the front display together, and determining whether view of the front display is secured at an eye level of the occupants of the second row seats.

What is claimed is: 
     
       1. A method for controlling a display viewing environment of occupants in a vehicle with occupant seats forming a plurality of rows, the method comprising:
 in response to a result of a viewing state determination being that at least one first occupant of one or more first seats in a first row of the vehicle, and at least one second occupant of one or more second seats in a second row of the vehicle, are in a state of viewing a front display together; 
 performing reclining or vertical level reduction of at least one of the one or more first seats; 
 determining whether view of the front display is secured at an eye level of the at least one second occupant; and 
 moving the at least one of the one or more first seats in a first direction among left and right directions and moving at least one of the one or more second seats in a second direction opposite to the first direction among the left and right directions. 
 
     
     
       2. The method of  claim 1 , further comprising:
 performing respective vertical level increase of the one or more second seats in response to a view of the front display at the eye level of the at least one second occupant being determined to be unsatisfactory. 
 
     
     
       3. The method of  claim 1 , wherein the vehicle is a purposed built vehicle (PBV), and
 wherein the at least one of the one or more first seats and at least one of the one or more second seats include a respective occupant footrest. 
 
     
     
       4. The method of  claim 3 , wherein the respective occupant footrest of the at least one of the one or more first seats further extends forwardly from the at least one of the one or more first seats when the at least one of the one or more first seats is reclined, respectively. 
     
     
       5. The method of  claim 3 , wherein the occupant footrest of the at least one of the one or more first seats is respectively rotated in a direction opposite to a direction of reclining rotation when the at least one of the one or more first seat is respectively reclined. 
     
     
       6. The method of  claim 3 , wherein a respective headrest of the at least one of the one or more first seats is rotated in a direction opposite to a direction of reclining rotation when the at least one of the one or more first seats is respectively reclined. 
     
     
       7. The method of  claim 6 , wherein a respective neck support of the headrest of the at least one of the one or more first seats protrudes when the at least one of the one or more first seats is respectively reclined. 
     
     
       8. The method of  claim 1 , wherein a respective armrest controller of the at least one of the one or more first seats displays a function of controlling a reclining-related operation when the at least one of the one or more first seats is respectively reclined. 
     
     
       9. The method of  claim 1 , wherein there are two or more first seats and two or more second seats, and
 wherein a movement in the first direction and a movement in the second direction are performed such that one of the two or more second seats is moved to be positioned at a spacing between seats in the first row. 
 
     
     
       10. The method of  claim 1 , wherein, when there are two or more first seats and two or more second seats respectively, at least two of the two or more first seats are connected to each other to form a first group and at least two of the two or more second seats are connected to each other to form a second group,
 wherein seats of the first group rotate in a first direction, and seats of the second group rotate in a second direction opposite to the first direction, and 
 wherein each of the two or more first seats is configured to rotate individually to face forwards, and each of the two or more second seats is configured to rotate individually to face forwards. 
 
     
     
       11. The method of  claim 1 , wherein the viewing state determination is based on respective gaze recognition of the at least one first occupant and the at least one second occupant. 
     
     
       12. The method of  claim 1 , wherein the front display includes a first display area for communicating with the outside, a second display area where a transparent mode and a specific widget display mode are switched depending on a driving mode, and a third display area for displaying control information. 
     
     
       13. A system for controlling a display viewing environment of occupants in a vehicle with occupant seats forming a plurality of rows, the system comprising:
 a first row controller configured to perform reclining or vertical level reduction of at least one of one or more first seats, in response to result of a viewing state determination, by a central controller of the system, that at least one first occupant of the one or more first seats; in a first row of the vehicle, and at least one second occupant of one or more second seats; in another row of the vehicle, are in a state of viewing a front display together; and 
 a second row controller configured to control the one or more second seats based on determination, by the central controller, on whether view of the front display is secured at an eye level of the at least one second occupant, 
 wherein, when there are two or more first seats and two or more second seats respectively, at least two of the two or more first seats are connected to each other to form a first group and at least two of the two or more second seats are connected to each other to form a second group, 
 wherein seats of the first group rotate in a first direction, and seats of the second group rotate in a second direction opposite to the first direction, and 
 wherein each of the two or more first seats is configured to rotate individually to face forwards, and each of the two or more second seats is configured to rotate individually to face forwards. 
 
     
     
       14. A purpose built vehicle (PBV) for providing a customized service to each occupant, the PBV comprising:
 first row seats, in a first row, and second row seats, in a second row behind the first row, wherein the first row seats and the second row seats are individually movable based on gaze directions of respective occupants; 
 a front display including a plurality of partitioned display areas, wherein a central display area among the plurality of partitioned display areas supports a display based on a common display mode; and 
 a controller configured to control at least one seat of the first row seats and the second row seats so as to secure a view of the front display at an eye level of at least one occupant of the second row seats when the central display area of the front display operates in the common display mode, 
 wherein the controller is further configured to move the at least one seat of the first row seats in a first direction among left and right directions, and move the at least one seat of the second row seats in a second direction opposite to the first direction among the left and right directions.
